Membrane crystallization is applied in this work for the separation and recovery of Na2CO3 and Na2SO4 as high purity crystals from aqueous solutions. These mixed solutions are for example produced when CO2 and SO2 are removed from flue gases by absorption in an alkaline solution containing NaOH. The application of membrane crystallization leads to a reusable product (i.e., Na2CO3 and Na2SO4) of industrial...
Reverse osmosis and membrane crystallization are evaluated in this work as stand-alone and integrated technologies for the recovery of Na 2 SO 4 from aqueous solutions. When SO 2 is removed from flue gases by absorption in an aqueous solution and reacts with NaOH, a reusable product (i.e., Na 2 SO 4 ) of industrial interest can be obtained.For stand-alone reverse...
